To answer my own question, I think it is some species of Dileptus.

Can anybody tell me what this is? Thanks

Thanks!

I had more dots than are visible there, and they were smaller (or the cell was larger), but I'm fairly sure that they were the same thing.

Thanks, 75RR, fo the ID. Regarding the moving dots, bacteria seem like a good possibility, but I don't know that the chlorophyll pattern indicates damage. Aside from the fact that it is symmetric, it appears that some Cosmarium sp. are like that, such as this one: http://www.digicodes.info/Cosmarium...

Does anybody know what this is?

I wish I had video. It is full of little dots (more than show up in the photo), and they are bouncing around quite rapidly. This makes me wonder whether it is a stage of an algal (diatom?) life cycle that is full of motile sperm.
